The only people who had those pagers were Hezbollah members. Hezbollah has been lobbing missiles into Israel, killing civilians including children and forcing an evacuation. They picked a fight, why should there be an expectation that Israel just sits back and takes it? Don’t get me wrong about Gaza, they have gone way too far there. But Hezbollah seems at least somewhat justified.
44% children, 26% women, 30% men. Gaza is about half under 18, so that’s nearly randomly killing people. That said, these are only confirmed fatalities, so presumably susceptible to bias.
